Mycologia 
discovered some very interesting diseases of trees in connection 
with his work on the chestnut canker, and the results of his 
studies will shortly be published. 
The January number of the Journal of Heredity contains three 
of the best popular articles yet published on the chestnut canker. 
Dr. Metcalf gives its history and characteristics, with a strong 
argument for careful inspection of future importations of nursery 
stock of all kinds ; while Mr. Van Fleet and Dr. Morris tell of 
immune strains and resistant hybrids that may save the chestnut 
to horticulture if not to forestry. 
The fifth annual meeting of the American Phytopathological 
Society was held at Atlanta, Georgia, from December 30, 1913, 
to January 3, 1914. The full program was completed with more 
than usual dispatch and opportunity was afforded for valuable 
discussion of the papers, owing to the method recently adopted 
of preparing a printed abstract of each paper in advance and 
presenting the papers in the form of abstracts only. As these 
have been widely distributed among mycologists already, they 
will not be repeated here. 
A box of truffles was sent to the Garden last autumn for our 
examination, with a note requesting information regarding their 
food value. Later, the sender of this material made a visit here 
and stated that the truffles had been collected in the vicinity of 
New York through the aid of a trained dog imported from Italy. 
The specimens were filed away in the herbarium for later study. 
In November, a second package of these fungi was received 
which was said to have been collected in New Jersey. A micro- 
scopic examination of these plants showed them to be two dif- 
ferent species. Later, a third collection of the plants was sent 
for examination, which collection was found to contain some 
examples of both of the species previously sent. These plants 
were of especial interest to us since they represent the only two 
specimens of the genus Tuber in our collection from America.
